Hi guys I have a early 80s QT10 that needs work on the spindle and I need some help. The spindle was perfect in this machine, never made a sound. But today it suddenly went downhill. In about 15-20 minutes it went from perfectly quiet to a very noticeable bearing noise. I cant understand how it went downhill so fast? Machine has the 3600 rpm spindle and it was only running around 1500 rpm, and couldnt possibly be doing easier work then todays job which was skimming 1/2" rod down to 12.5mm, only taking off 4 thou all day long?? Anybody have any ideas on what could have happened? Something get past seals maybe?
Where do I start with this? How does it come apart? Does the whole headstock need to be removed or does the spindle just slide out? Is there a cartridge that slides out of the headstock casting or do the bearing races fit directly into the casting? Does all the sheet metal need to come off? Anybody have a cross section drawing of the spindle?
I will need to do the work myself with help from you guys to make this worth fixing. Going to be hard to justify the cost of sending the spindle out for repair on this old machine.
